(CNN) - The niece of the Rev. Martin Luther King, Jr. said that her uncle would approve of conservative talk show host Glenn Beck's "Restoring Honor" rally unfolding Saturday in front of the Lincoln Memorial in Washington, the same place where the civil rights leader delivered his "I Have a Dream" speech 47 years ago.

"If Uncle Martin could be here today, he would sure commend us of giving honor where honor is due," Alveda King told a large, cheering crowd.
